No, just practice instead of writing blogs about 'what if'. Also, aim for improvement rather than a color, eventually you'll get there, setting up premature expectations will kill the motivation midway.

Why set such high goals so early man? Its okay to set your goals and have high spirit, but this goal seems a bit unrealistic unless you have some have had some training in maths or cp earlier. If not, for now, aim to become a specialist and then gradually increase your limit.

No, just defeat your past first.

That's the main goal.

Just chill and enjoy CP first, rest will happen eventually. All the awesome rated people on Codeforces didn't start competing for the sole purpose of becoming red as soon as possible.
