18yo guy, not knowing the next step for improvement

Hello BHW community,
As the title says, I'm an 18yo guy who doesn't know what is the next step for my overall improvement.
I'm actively hitting the gym for about 1 year now and I definitely improve my body a lot since I started one year ago. Recently I also started to care a bit more about my nutrition.
I watched endless amount of videos for self improvement, how to make money online and what not.
I was first interested in making money for a long time now, about 4-5years ( I was like 13-14 years old). Scrolled endlessly through a lot of forums in hope to find anything that works, anything that could make me a solid income over and over. As you can tell, I failed a lot of times and by a lot, I really mean a lot!
There were 100 guides that I've read, ebooks and what not but nothing helped cause those were some crappy ebooks with no good information.
I have a stable job, making me okay money. Enough to invest in something)

Things I've tried: Sports betting ( Though It was easy money); Crypto (Thought it was easy money), Instagram Account management (no success)
Some reddit ebooks (no success), CPA (Made about 150$, It was a good try)
And I'm currently trying affiliate marketing cause I saw that it is a good opportunity

Could anyone help me to do following things:
1) Stop caring too much ( I care a lot and I always overthink about things that I do/have done. It puts a lot of stress on my back and I cannot really focus on something when I have a lot of stress)
2) Suggested Ebooks from the marketplace and where to find them ( I have read a lot of good things for the ebooks on the BHW marketplace but I cannot find any, if someone could link me up with a few good ones
3) Is there anything else that I need to know? (I know that there's a lot of older people here, and I trust and respect hearing an advice from someone who's already been through something)

Hey brah you’re going through similar as me,
my advice to you which is working for me as well (same age) is literally tell yourself like physically speak the words ‘fuck it’ whenever your hesitant to try something
for example,
if you catch yourself on TikTok too much say fuck it and delete it or log out of your personal account keep your ‘business one’. Can’t be bothered getting up fuck it kick the sheets off. Once you start waking up to yourself and realising wether you do or don’t do something, the world still spins and will keep spinning.

The problem I had and am having is I’m coasting through life way too much, living on autopilot.
Start tracking what you are actually doing on a day to day basis.
Track how long you spent doing x how long you spent doing y.
Track how many games of z you played etc
Start tracking what it is YOU are letting yourself do without even realising it and I guarantee 10000% you will feel some sort of hatred or disgust towards yourself. This feeling is good and means you care about yourself and want to change for the better.

My favourite quote I recently heard

Your 18 year old self hates your 16 year old self for not starting sooner. Do not let your 25 year old self think the same.
