I'm really bored and tired of my lifestyle, but im not really doing anything about it. Idk what my problem is by i always play it safe, always scared to get out my boundaries and do more. how can I man up and just be the person I want to be. I've changed my mindset and think more optimistically towards the future, but I have so much self doubt i don't know what to do.

BG Info: 21, I try to do everything the books and articles tell you like "read, get some hobbies, do some fitness, meditate" and all that but as far as socially and being successful career wise im really lacking.
