Not since I was 12.You dont just roll up and play a game sometimes without planning it all out first?
Thats all it really is, you just have to put the game aspect before the 'i need to be this kind of character' aspect.
I don't get to play very often (nearly every DM). I legit build characters for fun in my spare time. I have a "folder" of character ideas I want to try. Additionally, I rarely like playing the same class twice in a row. And most games I play on tend to focus on specific settings or tropes (Ravenloft, Spelljammer, etc) and we don't always play in the same setting for two different campaigns. All of this really puts a strain on "I'll just let random chance determine what I'll play" because I want my character to fit the setting, be something I'm interested in playing, and be something I'm willing to play for months if not years.
Maybe if I was playing a Basic or Basic-inspired retro game for a short while, I'd be willing to let the dice fall where they may. But any game that is going to require me to play the same character for years and assumes I am building them with all the bells and whistles of a 5e character (species, background, class and subclass, feats etc) you can be damn sure I'm walking in with a concept of what I want to play.
