How To Set Short Term Goals?

5 Secret steps to set short term goals:
Secret #1: Grab a calendar. Pick a short term, manageable 3 to 6 month period to set your goals in. Short term goals tend to get you into action right away, are easier to visualize, and because of their short term nature they encourage you to set realistic, easy to accomplish goals.
Secret #2: Pick just 2 or 3 goals to work with. Don’t get overwhelmed by trying to change every area of your life. Just pick a couple of areas that you want to begin changing in the next few months.
Secret #3: The goals you pick don’t have to be fully accomplished in the time period you’ve identified. This is the key! Rather, what you’re looking to do in the next 3 to 6 months is to simply develop momentum, establish a pattern, and begin getting you excited about your life again.
Secret #4: Write your goals down. You’ve heard over and over again how much more effective goal setting is when you write your goals down. It’s totally true. Once you’ve identified your 2 or 3 goals, write down in detail what it is you want to accomplish, or what stage you want to be in at the end of the time period you’ve chosen.
Secret #5: Make a list and start identify right now, today, what actions you can take to move you closer to your goals. Can you join a gym? Buy new walking shoes? Make 10 more cold calls today? Fill out a profile on a matrimonial site? Take your kids to the park tonight? Make a list of actions you can take today and take them!Do the same thing tomorrow and get in the habit of taking an action each day to move you closer to your goals.

Yes after writing down your goals like Pushti said, it is necessary to imagine and visualize your goals so that you have clarity on your thoughts. Imagine them happening already, act as if you have already achieved your goals so that it gives you a positive vibe to take further steps in order to achieve your short term goals for real this time.
