Here is a problem with success: expectations begin to rise. No sooner than a task is completed, there is an immediate need to ratchet up performance. This can be a blessing or a real pain. It can be motivating or a depressant.
Almost every human I know needs physical and psychological rest between accomplishments. Almost no one can handle the relentless pace of change that is thrust upon them. Assess the capacity to absorb change and the need for recuperation from the prior effort in your audience before you hand out goals.
More important, as you challenge yourself, do not place an undue burden upon yourself. Give yourself time to recuperate before you take on the next level of achievement. In other words, don’t be a martyr unless it is really, really worth it.
