From my own experience and my observation of others, I've discovered a few different things about what steps are necessary to move from being in a place you don't want to be in your life to pursuing and achieving exactly what you want.
The first and most important thing you need to do is to know what you want. It doesn't do any good to chase a dream if you discover at the end that it wasn't even your dream! Make sure your goals are yours and not someone else's, and not what you think they should be, but what you want. Too many people don't know what they want, so they spend their lives chasing one thing after another, thinking each new thing will be the one that makes them happy. I'm not sure what is worse - not making the effort to chase anything, or chasing something your whole life only to discover it's not what you wanted! Take the time to sit down and really think out what it is that you want out of life. Go through each area of your life and write out what you want it to look like. You must know exactly what it is you want out of each of those areas. Only then can you take the steps to achieve the results you truly want.
Often times if you feel low or depressed, it is because you are not doing what you know you should be doing. I've discovered this in myself in the past. I've also heard comments from others around me about their lives, and the root of it is based on this. They know they should be taking action on something, but they're not. They know they have the capability to do better, to do more with their lives, but they're not. When you know you should be doing better or doing more to pursue what you want, when you know you are not meeting what you are capable of, you beat yourself up mentally over it. The solution is simply to start taking action on those things. It may be something small or simple at first, such as making a phone call you've been avoiding, or it could be starting your business plan. Whatever it is, it just needs to be something that is taking you in the direction that you know you should be working harder to get to. It doesn't have to be huge, it just needs to be action. Stop putting it off. And trust me, when you start taking these small steps you will feel relief, as well as start building your confidence and sense of worth. Once that happens, the next steps are easier and it creates momentum toward your goals.
The last part of the equation is consistency. Writing out what you want and then taking the first step is great, and will start you on the right path, but the right path can't take you to its destination if you are not taking additional steps. This is not an escalator, this is a stairway. You don't get to take one step and sit back and think you will keep making progress. You have to keep taking action. Consistent action is necessary to keep things moving, or you will find yourself right back at the previous step; knowing you should and can be doing more. Don't let that happen! Once the ball gets rolling it's easier to keep it rolling. But when it stops, it's hard to get it started again. Don't let it stop; keep taking steps every day that help you get closer to the life you want. You deserve that life, and don't let anyone tell you any different.
I encourage you to take these steps seriously and go through them one by one. I promise you it will change your direction and change your life. Keep your goals, what you want your life to look like, in front of you on a daily basis. Remind yourself what you are pressing towards. Know what you want, take action on those things, and do it consistently and you will discover abundance.
