The more you know the better you become. So learn both forms! To memorize a character, it is best to break the character into its components and radicals. Know the common radicals well. Traditional forms has more semantic encodings. For example, 風 wind consists of the wavefront (the outer part). Inside is the radical for insect. The slant stroke represents the insect's wing. It is so written because ancient Chinese believe that wind comes from the beating of insect's wings. This is how I can memorize my characters well. Learning Chinese in this way also teaches you the culture and philosophy. The simplied form, 风 contains no such clues. So it is more difficult. 如 = if. You see it contains a woman and a mouth. Women's words are considered iffy and cannot be taken seriously. Chinese is the most sexist language. 好 is good because the woman has given birth to a son (not a girl!) 字 = words because only sons are to be educated in the house and has to learn words. 安 = peace since the woman does all the housework and the man is at peace. 婦 = matron since the woman is holding a broom. 家 is family. The pig under the roof is more important than a woman since pork is the favorite meat for the Chinese palate. So it brings commerce in selling pigs. With money, there is family. There are many many more examples. This is the key to unlock the secret of Chinese characters.

I don't suggest you to learn 繁体字, it is not used in China, only in Hongkong and Taiwan. And it will be better if you can make the picture clearer or write down here so it will be easier to correct for you.
