Believe in yourself!
Isn't it strange how we have so much more faith in others than we do in ourselves (I'm always reassuring friends and family who doubt their abilities and choices – I have complete faith in them!).
I'd always wanted to do self-led work alongside commissions but I was worried that I wouldn't know what to paint, that people wouldn't like my own artwork, that I wouldn't 'find my style'. . .
In the end I just decided to go for it: it doesn't matter where you start as long as you begin.
I've found doing a challenge, entering competitions and choosing a theme for my work really helpful. It focuses my ideas and helps me feel connected to a wider artistic community.
The main thing is to trust your instincts. Don't rely on feedback from others (although lovely comments on social media are always a boost). Your gut feeling is usually the right one!
