A Bunch of Ways to Figure Out Who On Earth Your Blog Should Be For

* Observe carefully. Pay close attention to details. Pay extra close attention to the blogs and people whose examples you want to follow. Hang onto their every pixel and word.
* Experiment. The only way to know if a seed will grow into a tree is to plant it. If it grows, it’s a good seed. If not, either it’s a bad seed or its growing conditions are too poor. Similarly, you should have the courage to try things out on your blog and in your blogging routine. If they work, keep doing them. If they don’t, stop and consider changing your approach or replacing your idea.
* Imagine the future. Think of the possibilities and probabilities involved. Should your blog become a company? Depends in part on how many gray hairs or wrinkles you think that would give you.
* Remember the past. What to write about? Well, what worked before? That’s one good approach.
