I'm already decent at makeup, I work out too much to make it worthwhile to bother with hairstyling unless it's for an event, but I did book myself some makeovers at Sephora this year. There are lots of simple tutorials online, just focus on one thing, e.g. eyes or skin, and definitely invest in some tools. I used to hate how foundation looked on me til I got a set of brushes and started using those to apply foundation/concealer/highlighter/bronzer, and blending with a sponge. You don't have to spend a fortune, I got a set of like 30 brushes on Amazon for something like $50, and buy generic blending sponges.
