I have been planning several books for the last few years but I just can't seem to get started due to a lack of confidence 
I feel I will be wasting my time, that I am not clever enough to do this and that I can't express very well what I need to say.
I have started to write a couple of times but it just doesn't read/flow right and I end up deleting everything.
In short I think I am not intelligent enough. I am worried that my grammer is not up to scratch (along with my spelling)
and I often have to use a dictionary or ask my dh what something means

Did/does anyone else feel like this?
Has anyone got any ideas on how I could get started?
How could I 'smarten up'?
I did think about a creative writing course, but I just couldn't justice the money.
