Writing is such an important part of every day life it's too often taken for granted. There are a million things to write about, but every once and while all of us get stuck developing inspiration for what subjects and topics will give readers the a-ha moment! Go to any forum on the internet and see if you can't automatically find something to comment on. There is no question everyone can devise an opinion on something. So, if you can opine on it, you can write about it!
On the flip side, this process of creating inspiration to adhere to your ego should flat out be dropped into the black hole of non existence. If you write to impress yourself you will never really share valuable ideas, and your personality will never manifest in it's purest form. Philosophy 101 on writing should be, "Just Write!" Yes, some writers are better than others, some writing flat out stinks, some writing is genius, some writing is monumentally depressing.
However, that's what makes life and reading exciting. I love to read a piece which has been written extremely well, but I would always rather read something which has inspired me or given me an idea I haven't ever read or thought of. Personality in writing is much more important than any holier-than-thou perfectly written article. Although, let me caution it is still important to strive for correct form. In order for people to easily read what you write, they need understanding and clarity.
Write the best you can. Commit to accuracy and grammatically correct writing, but never let these things outweigh the attribute of YOU in your writing. You can edit til cows come home, but trying to relay ideas and slight twist is something with which there is no precise science. Want to give yourself something to write about immediately? Here is a very gauche little tactic people use without realizing they are taking advantage of their mind's naturally ability.
Pick any word and associate it to another word. Cracker->Peanut butter->Peter Pan->Disney Movie ->Cartoon-> Drawing->Still Life->Portrait, etc...
It easily natural to do this because we create this process all day long without even realizing we're doing it . If I wanted to write an article at this site which is a blog about writing, a simple association has instantly conjured in my mind.
How adding "pictures" adds value to articles.
How did I think of this? I looked at the words "Still Life and "Portrait" and immediately "Picture" was associated. I would not consider this rocket science in any way. Association is a greatly effective technique to find topics to write about.
To just writing....and getting better at it!
