You will be amazed at how quickly your skills will build, even if you're not specifically trying to work on a certain skill. I can't tell you how many times I would get frustrated with a project and throw it in a corner or toss it in a closet for 6 months, then bring it back out and voila! somehow the problem I was having isn't as frustrating and I now know how to handle it!
Now when something gets me frustrated, I patiently put it aside for a couple of months and work on something else. I know when I go back to it I will be ready and able to solve the issue.
Another tip - when you're feeling indecisive about design choices, or not sure which direction to go, tell your brain to dream about it every night until you come up with something you like. Works every time for me.
