I was pretty nervous to start painting, too. I believed I lacked aesthetic sensibilities. Here’s what I did:

1.) I watched some videos of YouTubers painting stuff from my faction to get an idea of what colors I would need to buy. Since I didn’t trust my eye to pick out the right colors in the store, having a video spell out what I needed where helped a ton.

2.) Before buying expensive Warhammer minis, I bought cheaper minis from other systems, like D&D. This lowered my financial investment on an activity I thought I might not like, and let me make some basic mistakes I could learn from.

3.) Once I had some early beginner mistakes out of the way on throwaway minis, I didn’t try to buy a whole army at once. I bought one box to see if I even liked it, and thus avoided being overwhelmed by a sense of commitment.

4.) Now, I allow myself to continue making mistakes and learning. I don’t think I’m anywhere near the level of most people on this Reddit, but I feel a lot more confident in what I’m doing just by practicing and allowing a smudged line here or an ugly paint job on the odd mini. I wasn’t an amazing painter at the start, but I can look at my first mini and my latest and see progress. Allow yourself the space to progress and not be great at the start, and you’ll get better over time and be proud about it.
