Practice the following methods & techniques for a successful  memorization of words.
Use the command words! Combine them with names of things you'd like to know. 
Use real objects or pictures of items.
Interview Spanish speakers! List items by topics like food, clothes,  sports, occupations etc … Ask which ones they like or dislike ( … le gusta a 
Ud … ¿no te gusta? …)
Collect Spanish children's books, comics, and schoolbooks. While reading,  point to each picture and name it in español. Do it with a kid or a friend.
Make an audiotape. Ask native Spanish speakers to read aloud a list of  words that you need 
to know. Tape different sounds and pronunciations. Offer to make an English tape in return.
Draw pictures of items in special categories and label them. The "un-artistic" can cut out pictures from magazines.
The most natural way to acquire action words is by having someone command you "to do something". On the other hand with these "visuals" you can begin to "talk" about what's going on.
Get friends involved. (Use affirmative, negative and question forms). 
These activities work better when a native Spanish speaker assists you.

THE SECRETS OF SUCCESS

Get the habit of using Spanish regularly.
Constantly memorize vocabulary through "word - picture" association.
Follow the practice tips and activities above mentioned.
You don't have to speak until you feel like it.
But you can't make any excuses for not learning.
Add your own ideas on how to practice and improve!
Por favor! Go for it and have fun! …
