Need direction

Hello everyone.This is my first time actually posting here,but here we are. Basically I am not comfortable or happy with who I am currently,I want to achieve some goals but whenever I have to actually put in effort I lose all motivation and go back to doomscrolling or binge-watching TV shows.I was hesitating starting gym for almost 2 years,and 4 months ago I started it,and looking back I became quite obsessed and never missed a day.I know,deep down,if I start doing things I want I will continue doing them,but Im missing the first step as always.The start is the hardest thing for me,and it doesnt help that my mind is constantly telling me I can do better even when Im being productive.Other than that,I struggle with nicotine,but in a way I dont want to quit yet,and most times I quit is cause Im short on money,so basically I treat it like a reward of some sort.There are probably reasons for this from my past,but for the sake of simplicity I believe,for now,this is enough.Thoughts?
