Here's the most cliché phrase you'll ever here: you only live once.
But seriously, there are sooooo many things you can do to make the time you are on planet Earth the best time. Don't let anything or anyone hold you back from doing what actually makes you happy, trust your heart and what it will actually be good for you. If you want to text your crush, go for it... if he doesn't reply or whatever then move on, text someone else, live your life.

If you want to go dancing and kiss some guys, go for it... and if you don't want to do that and would rather spend your night watching To All the Boys I've Loved Before, go for it. If you want to watch an animated movie on the cinema and no one wants to go with you, go alone, who cares!!! Seriously, the other day I went to watch SmallFoot by myself and I was REALLY EXCITED lol, when I got there there where like 2 other people by themselves too... literally no one cares if you go alone, go watch that animated movie or whatever. Don't miss the chance to do something you REALLY want to do just because no one wants to go with you, you'll find people on the way.

You literally only get one of these lives, so take good care of it, do what you love, spend it with people you actually care about, be happy with yourself... you deserve a love as big as the sky and a life as beautiful as a diamond.
