CEC is totally right. The more solving-strategies you know, the faster you become in solving sudokus. Many sudokus, unsolvable before, become boring and grey suddenly. But be sure, there are still more sudoku-challenges waiting for you, after you have cracked the first easy levels. You will need more difficult sudokus from time after time. The more solving strategies, of which you will find a plenty in this gifted forum, you will encounter and master finally, the more you will become aware of the dimensions of logic to be necessary to solve even the hardest nut. And you will find out that there are different ways to solve and you may prefere one brute fast step or a series of easy but asthetic steps just according to your whims like a mountain climber which may choose the shortest but hardest ascending stony way or the long, relaxing and easy serpentine.
Anyway, you will be able to discover your own solving methods. For me, I'm glad when I find a solving-way which is faster and more beautiful at the same time than the way my computer-program offers me. I always try to find a nice solving-method according to the difficulty-level of the respective sudoku. Nothing is more inadequate than solving an easy sudoku, which requires a bunch of Hidden Pairs and Pointing usually, with a multiple forcing chain! It would be like shooting with cannons on sparrows. For the multiple forcing chain cracking many puzzles in one step see the link below (entry of 06.10.07, pictures 2, 3 and 4):

If you only want to find that right forcing chain, which solves the whole puzzle, go on! But this way may you deprive of a lot of possible precious solving-gems spreaded just before you on your path, like xy-wings, Sword- and Turbot-Fishes or even a BUG Typ 1, whose nice structures delight not only the eye but also the logic mind in our brain.
