I was a hiki-NEET for 5 years then worked with a therapist to deal with my autism and develop goals
now I've accomplished all my goals and I don't know what to do
how do you develop new goals when you already have what you want
I tend to identify long term goals then plot a series of short easy goals to reach them. If I wanted to become ripped, I would join a gym, then learn how to lift a barbel. Next I would plan beginner sets and good times to do them.
Really it all starts with deciding what you want. If you can visualise a series of short goals, with enough time you can achieve anything.
