How can I master tenses?

[daniel]

In my writing, the most commonly recurring problem people see is I continually use different tenses. How can I fix this?

Practice with one tense for a while and then move onto the next once you have it down to a science. Start by reading several books of the same tense then write a few short stories (or even a full novel if you have the time) of the same tense. I'd be surprised if you didn't show significant improvement after that
