1. Read 1 book per week. Reading is a good way to keep your brain active. With just 30 minutes per day you should be able to read one book per week, or more than 50 books per year.
2. Solve puzzles. Quizzes, word games, etc. are all good ways to exercise your brain.
3. Think positively. You are what you think, all the time.
4. Make fast decisions. Instead of thinking for one hour wherever you are going to do something, make your decisions as fast as possible (usually less than 1 minute).
5. Wait before buying. Waiting 48 hours before buying anything is a tremendous money saver, try it.
6. Meditate 30 minutes per day. A great way to gain clearness and peace is through meditation. 30 minutes are not a lot, but enough to get you started with meditation.”

1. Use an inbox system. Make the habit of keeping track of all the ideas and things that comes to mind. You can use a notebook to do this, and then sync everything on your computer.
2. Prioritize. If you have a list of things to do, where do you start? One way is to prioritize your list. If you are in doubt, ask yourself: “If I could only accomplish one thing today, what would it be?”
3. Plan, but not too much. Planning is important, and you should decide in advance what you are going to do today or this week. However, planning for more than a few weeks is usually inefficient, so I would not worry too much about that.
4. Wake up early. Waking up early in the morning is a great way to gain extra time. I personally like to wake up at 5 am, so that by 9 am I have already accomplished what otherwise would have taken me many days..
5. Check your email only twice per day. Email can easily become an addiction, but it’s usually unnecessary to check it every 10 minutes. Make an effort and check your email only once or twice per day, see if the world will still rotate as before after you try this.
6. Eliminate unimportant tasks. Being busy all day does not mean you are doing important stuff. Eliminate every activity that’s not important, and focus on what really matters.
7. Clean off your desk and room. Having a clear room and desk is important to maintain focus and creativity.
8. Automate. There are a lot of tasks that you need to perform every day or every week. Try to automate them as much as possible.
9. Set strict deadlines. When you do something, decide in advance when you’re going to stop. There’s a rule that states that you will fulfill all the time you have available for completing a task, so make an habit of setting strict deadlines for maximizing your productivity.
10. Take one day off per week. Instead of working every day, take one day off per week (for example sunday) where you are not going to turn on your computer. Use that time for doing recreational activities like going for a walk.
