For you to truly change something about yourself or an aspect of your life that you don't like anymore (money, career, relationships), you literally have to go through hell and back with each of those aspects becoming so tired of that particular lifestyle that you tell yourself "enough is enough, this cycle of unhappiness ends today!"
Until that pain or overbearing emotional stress consumes you and the tears you've shed haven't become brutal and by the tons, nothing will change and neither will you.
True change occurs when you reach that point of not being able to withstand it anymore.
If you aren't happy in the relationships or friendships your in, you have to change it. Evaluate was aspect of it you don't like and change that.
If you aren't happy about the money you have or the money you lack, go within yourself and see why? What about it do you not like? Do you have no freedom or extra wiggle room to go and buy something you've been wanting or having in your thoughts for a while?
If you don't like your career, what about it is dragging you down?
If you feel the need for change but don't know how entirely to do it, the best way you can start a change is by going deep within yourself and focusing on what you really want.
You have the answers for all your problems, trust in yourself and your intuition to guide you and it will.
