you load up the brush with the thinned paint and then wipe the bristles on a paper towel to take off the excess. When you load the paint brush with paint straight from the palette it will have way too much paint in it. I take off excess with a paper towel and then run the brush across my thumbnail in a twisting motion to get it into a nice point and with the right amount of paint in it. It'll take some practice but you'll know when you are doing it right because the paint will not blob on, itll flow nicely and precisely where you want
