I've always had projects growing up, building a go kart out of metal tubes, welding at 13 then using a s10 engine and tranny only to discover it bent the frame as soon as I put it down lmao. Other times it was mating a Toyota forklift mast, handled and hoses to a John Deere 5510 for peach harvest . But the best time I learned about life and how to approach everything was wrenching on my lil 84 Vette. Trying to squeeze as much power out of a 402 small block , changing carb jets, fidling with timing air pressure etc drag racing is a lot of fun.
After all those experiences, celebrating minor victories and accomplishments is SO important to maintaining the Momentum of your energies. Congratulate yourself, appreciate your efforts, love your setbacks learn from them but always be positive and enjoy life. At the end of the day we all do it for feelings, how good you feel and how good you make others feel is how memories last, physical material things will always fade.
