The problem with small difficulties is that if you get too close to them, they seem large. Like mosquitoes, even though they are small, with enough of them pestering you, you can find yourself entirely taken up with dealing with them.
With mosquitoes, you might endure them, and this is one way to deal with them if you have to. You can also endure your small problems and fight through them as if they were a swarm of mosquitoes. Or you might step back inside to a sheltered place. Stepping back is also a good way to deal with small problems. Step back and gain some perspective and see the small problems for what they are: small and insignificant in the bigger frame you view them from. You will still deal with them, but regaining that perspective reduces the irritation that they bring on, and helps you deal with them with great patience and equanimity.
