Should I start writing once again ?

Wonder when was the last time I thought of writing a short 

story. Probably a long time back -when idea of writing out

something that stirred my inner self -often possessed me to

such an extent that I was compelled to surrender. But those

days have past and -now-writing out even few lines seems to

tax my brain to no end.

Under the present circumstances I am seriously requested by

someone-who is very dear to me-to once again pick up my lost

pen and get going  !

What should I do ?
