How good does it feel to have something you've waited and worked hard for years finally come into fruition?

The feeling can best be described by one who has achieved the success after hard toil for years together and got rewarded for it. When one becomes a lottery winner, it comes as a bolt from the blue. But if one had a particular goal to achieve, sweated hard year after year in a planner manner and at last success came at one's door, the feeling was heavenly and can not be described in language.
