When you're shifting while climbing you really need to anticipate a shift and begin changing gears before the grade of the hill becomes steeper. If you're trying to shift with any substantial pressure on the pedals there's too much tension on the chain to allow the derailleur to move the chain up on the cogs. If you've gotten into the grade and cannot easily shift it's better to dismount and spin the pedals as you lift the rear wheel and move the shifter lever to get into a gear you can maintain on the grade. Keep practicing, it will become second nature to anticipate a gear change in advance of the increasing grade of a hill.
Good Luck!
