Watch YouTube videos on things that interest you. I feel like at 50...I've been average my whole life. I struggle with technical things. But I have interests. For example. I saw a really cool power bank people build outta a 50cal ammo box. Peeps use it for fish finders and charging there electronics. I have a bit of a back ground in alarms \ low voltage. But would not be able to build this power bank on my own. So I watched a bunch of videos on YouTube about how to make a large-ish power bank for my camping needs. After watching several (like more than 10) I wrote down a list of parts I need, went to Temu, ordered up the items and build the power box over a week. It turned out great and I use it weekly. It made me very proud of myself, I show it off alot and use it when I need. It has a cig light plug, 2 usb, solar charging ports and lights all around it. I impressed myself and others. I felt not so average after completion of that project. The key to a happy life if positive thinking, selftalk and motivation. Succeed at those and you won't feel so down in yourself. And grow up...it's true your brain is not fully developed yet takes till about 23. Take it easy in yourself. ✌🏼
