Time is on your side
How frequently do you say "I don't have time"? Quite often, I guess. Every time we say those words, they make us feel weak and out of control. You are in control of your hours and your life.
I don't as easy as simply turning off the TV. But here are two steps that will help you take back control and get time on your side.
Be honest: do you Spend an hour or two visiting Weixin and QQ every day? Are you spending time with people that you don't really like just to please them? Are there meetings you attend that you can politely refuse?
It's time to get real about the hours that add up to a lot of dissatisfying nothing. Think how you can cancel daily activities that are not useful.
Change your language.
Words matter. They have power. Saying "I don't have time" is an excuse for not wanting to do something. Here are some good, empowering alternatives (选择):
"I choose not to start that project until next year."
""
"I'd love to go out this weekend but have important work I need to do first."
Get better at saying no. Use little pockets of time (friend running late, car stuck in traffic, meeting ending 10 minutes early) to do some productive thinking. All these things can add up over time more than you believe!
A. Identify your blocks.
B. But you are likely wasting a lot of it!
C. I really don't have enough time to do it.
D. Replace them with things that satisfy you.
E. Take no notice of all those unimportant messages on your phone.
F. I'd love to read that book — I'll get to it after my homework is complete!
G. When you don^ have a plan for your life, someone else will plan it for you.
—You'd better read the ________before you use it.
