Feels pretty good actually.
When I'm wasting my life, I like to think of, say... a random peasant living on the outskirts of the Frankish empire (bear with me). Lets call him Gerard. He grew potatoes. Was married to milkmaid (for some reason I want to say "milky-maid"). Gerard didn't have much going on except this. He died at 44. His wife died a year before. She was younger, but she had a miscarriage, and died along with her baby. Gerard didn't read, didn't write, didn't have air conditioning, maybe 3 friends at the tavern.. For the most part though, he managed. This was basically all his life would amount to, and he didn't know better. Relatively speaking, he had pretty good. There wasn't any war in his area.
Now my point is, this is majority of human beings throughout history. Next time you look for meaning and purpose, you might want to tell yourself to stop acting like an entitled wuss. You weren't guaranteed meaning. Your life is meant to be wasted, and you will be forgotten a 100 years from now, let alone a thousand. Not to be negative though. If you look hard enough, there is meaning in that. The only meaning you're ever going to find. The one that tells you to enjoy the small things and stop getting so depressed about some supposed destiny. Also, all of those people you're more envious of don't have that much better. And if they say they do, they're full of shit.
