I love doing my makeup. One thing that seems important to me is the order in which I do my makeup. if I do things out of my usual order I make tons of mistakes and have to correct it. If I do things in my normal order, I can even do a halfway decent job with no mirror (wouldn't recommend it though), I find that rather strange but maybe it is a muscle memory thing or something like that.
Liquid eyeliner may be more difficult, but I feel its totally worth it as I don't have to touch it up very often, even with the cheap stuff, while my cheap eyeliner pencils last no time at all, and even the slightest bit of moisture may make my pencil smear while my liquid stays on rather well unless makeup remover, baby oil, or similar is applied.
