The best strategy is to take your time and level up units and buildings as you go. Some quests are not attainable at your current level. An example would be lvl 24, build an armor shop. The armor shop is not available for production until lvl 27.

When a new unit is released, spend a few weeks getting your units' sp built up to level 4, 5 or 6 if possible. This will pay off at the next game level, where the enemies typically get harder to beat. Leveling up buildings that produce resources as you go will yeild more returns. It's better to have 2 level 5 iron mines than 4 iron mines at level 1..etc

Hope this helps.
