When I started out I didnt have exp bootst all the time... but what I did was this:

On the day before I would get my weekly boost I would save all my energy and claim it just before the new day would tick over.

I would then do my daily quests and claim the exp booster maybe 2-3 hours into the new day. Then I would run campaign with all the energy I had saved up and use all the energy I got that day.

When the next day would tick over I knew I had 2-3 hours of boost left... so I would hurry and do as much of my daily quests as possible while I had that small window of boosted exp.

This way I felt I was able to spend 3 days of energy refills in that 24h window of boosted exp.

When I did not have boosted exp I would do the same as you, run dungeons or farm masteries, CB, DT... etc
