To stay productive is the key when you are trying to do something big. I have found that when you do something with a mind to help others, you can stay more productive than when you are doing it for yourself. So here are some tips which I have learnt through my experience.
1) Find time for what you really want to do..
There maybe things that are more important than others. Find time for them. In short, its prioritizing your tasks. It cuts off unwanted time.
2) Eat, Sleep, Drink
You need energy to stay productive. Eat food and drink lots of water. Getting adequate sleep recharges your mind. All these habits sync together to boost your output. Thus paying attention to them is vital.
3) Have a Plan in mind
You should have a mental picture of what you are going to do next. Planning involves knowing what work and how much time you have in detail. The plan should be concrete and you should stick to it. Allow connections to happen naturally while you are doing but don't deviate much
4) Start Now..
Often the problem is that, after knowing and planning what you want to do, you can't gather yourselves to start. That's where your motivation and inspiration works and mainly the cause. If you take the decision and start, then everything will work well on due course.
5) Think and Appreciate yourself
Review your work and congratulate yourself for what you have done. This gives you satisfaction and an urge to do more. And thus its said 'Excellence is not an act, its a habit'.
