Completing Daily Quests is one way to get rewards such as gold and points, both of which you can spend in the corps store. Daily Quests are important for leveling your headquarters, getting resources, and useful perks. It is also beneficial to complete the Daily Quests each day as it will enable you to get prepared for upcoming events which you can earn even more rewards from.
Playing and completing a Daily Quest in a day should easily earn you the 2,300 points needed to unlock the activeness chest. If you are struggling to reach this points total it is probably because of one of the following reasons, you've been buying items, not got enough VIP, or enough stamina. To rectify this only use 3 VIP point cards each day, only use stamina when it is closest to the daily server reset time and buy 10 antennas.
