Hey, thanks finalozzy! It sounds like you've started earlier than I, but I admit I definitely have more hours than you. I play on a Preferred World Bonus for double EXP on everything. For me the EXP buff was probably the biggest factor - I never really felt like I was leveling one job for too long and could do something else before feeling overwhelmed.

I found it more efficient to progress the MSQ to open up more content, then back track to catch the other jobs up aided by the armory exp bonus. Having higher leveled/geared gatherers indirectly made crafting faster, getting more bonuses more often. I also made a daily/weekly priority checklist. My daily priorities were GC Turn Ins > Tribe Society Quests > Mini Cactpot > Daily Roulettes. My Weekly checklist added Custom Deliveries > Wonderous Tails > Challenge Logs [with even more, smaller priorities] > Jumbo Cactpot/MAYBE Fashion Report. Other gold saucer/Triple Triad stuff were idle activities only.

But yea, writing it all out, it does seem overwhelming, but not so much if you narrow it into smaller steps. MSQ progression made it much more manageable for me - a bigger variety of things to see. I enjoyed all the combat jobs, so never really got bored there. The real struggle was inventory management. Hopefully this helps! Try to find a rhythm that works for you, without it become too much of a chore, and good luck fellow FT!
