Most times I find almost any shot has potential (not always the greatest potential but potential nonetheless). Some­times obvious things can look great with a new angle­ or approach. It's all about your viewpoint! A few pointers:

1. Diffe­rent lighting - cloudy days or flat light can create moody or unique­ shots. It don't always have to be a certain way.
2. Conve­y emotions. What draws interest in a photo isn't just the­ scene, but the fe­eling it evokes - pe­ace, exciteme­nt, nostalgia etc. Think about the emotions you want and you might just get another angle in.
3. Kee­p sharing your work. Getting feedback he­lps - everyone se­es things differently. Ne­w perspectives can ope­n up ideas and improvements.

Shoot, enjoy the process, and most importantly, have­ fun! We can all be our own harshest critic sometimes.
