You could try a local writing group perhaps. They vary in many ways but can keep you going and it can be good to get feedback and swap ideas.
Or you may prefer to just get on with it. Free writing can provide a kickstart - just set a timer, pick up a pen and write whatever comes into your head. It can help one avoid the 'I can't do it, my work is not good enough' doubts which I hope you'll never have.
Have fun and let us know how it goes!
