Thoughts

Connect always yourself to what you become want to.

Trying will never let you down.

Read Read Read Technology.

Nothing other than True will honor your life. So, be True to yourself and others with your every action in each and every second of your life.

Be Connected. Be Updated. Be Innovative.

Your work never affects your interests. Go on learning on your interests and new and needed technologies by yourself. Really, You can feel that value later.

Do not think anything as technical. Just map them into real world analogy. It will give you easy understanding and will enable you to provide more optimized solutions by emulating them using real world objects at low cost.

Let's think. Algorithm is there.
