I agree, acting on time has numerous advantages; it gives you a head start among others and also helps build momentum going into the next tasks.
What I have learnt over the years is acting on time can be be a bit tedious most times because as human we think we have the a lot time but it has a great deal of benefits and little or no downsides at all. So I’ll encourage people to start early, get it over with and move to the next.
