I tried a similar method of jumping around from different planes, weapons and types of attacks and found that I was only learning a little bit about each.
Then I decided that I would only fly one plane - the A10c, first I mastered the start up procedures and instruments. Then take offs, flying to various way points, and finally landing.
Then I created very simply missions like placing 5 tanks in a small area. Then I would practice using the controls; DMS, TMS, operating the CDU's, finding & marking targets with the targeting pod, creating SPI's, slewing sensors to SPI's & mark points, and finally locking onto target with the maverick missile head.
Then I learned how to use the maverick missiles, then CBU 97's, CCRP delivery etc, etc...
After I felt I mastered a specific weapon and or sensor, I would select another and I kept going on, and this is what I'm still doing.
I still have a long way to go, but I feel great after I become proficient in one area that I've selected, which builds my confidence to try something new!
I hope this helps, and maybe i'll see you in the air sometime!!
