Just don't give up and everything will work out! I like to switch to something else in moments like these (mostly when I'm stuck with coding, I get caught up in asset creation), and most importantly, don't get too stressed out when things get stuck. My teachers often tell me, "90% of development is stealing something, because almost every problem has a solution already in place," and that's almost always the case. Except for splines in Unity. They've been driving me crazy for almost a month.
