Friction is helpful in situations like when you are standing on a hillside. Static friction between your shoes and the surface are stopping you from slipping. Friction is not helpful in situations like when you are pulling something heavy. Some of the energy you are putting into pulling is going into heat from kinetic friction and making your job more difficult.

Decreased friction is very helpful in working machinery, because friction causes wear and tear.Mainly its very helpful in moving parts. Decreased friction is also helpful in electric cables and wires, as reduced friction reduces energy loss via heat.

Friction can be helpful and not helpful it is not helpful when you are running because it slows you down hope that'll help!!!! ;)
Friction is helpful between car tyres and roads for grip. It is also sometimes used for heating as friction generates heat.
By using kinetic friction
Friction lets the drive wheel push you forward, and allows your brakes some bite. Friction make it possible to hold on to the bars. Friction lets you steer.
Helpful Friction.

Friction is necessary for wheels to rotate and nails to keep in walls.
Without friction, we couldn't walk or grip onto anything.
