[To become standard programmer and for scope life time ]

#1 is unattainable.

Even if you become a world expert in programming, you'll still make mistakes.

However, you can minimize bugs and solve them more quickly with the application of clear thinking and lots of practice. Try not to be too rushed when programming, whatever the pressures.

To foster professional relationships, try to make time to attend conferences which is a good way to meet other developers working in the same field as yourself.

Lastly, NEVER post your email address and telephone number on public websites such as this one. They're an open invitation to spammers of which there are a lot about.
