I start out with a general idea for a post. After doing a keyword search, my focus often changes. I go with my new idea because it will contain keywords that are what have been referred to as low hanging fruit. It increases the likelihood of being indexed.

Don't worry about the pace. We all go at our own pace mine is slow and steady. Hang in, we will get there.

Hi David, overthinking seems to be my problem too. But I just try to keep moving one foot forward at a time. Building a successful online business takes time. You might be moving forward slower than others but that is ok too. Just keep following the training plan and in time you will get a better handle at things.

I believe its part of the process to make it happen.
Don't be discouraged! Keep it up!
All the best,

I know exactly what you mean... As I get older the information I read and try to take in doesn't register and stick as fast as it used to... lol.
I find I have to do some of the lesson a couple of times before I get it.
As far as the content and keywords... I get my general idea then look at the keywords that might fit the topic. Choose according to the best stats.
Then write my content trying to get all my idea's across.
Hope this helps
Cheers

We all have our own way of doing things David. Whatever works for you is good.

Everyone does experience the writer's block from time to time. Just do the things you enjoy doing at such times. Taking short breaks as someone's already suggested does help at times.
I always find walking in the park, just being in tune with nature very refreshing and energizing.

Happens to all of us. Just be patient and I agree that organization does help. Sometimes I just take short breaks or go for a walk. Best of luck.
