Against Hesitating

Thanks to your "success," you now have something to lose. Because of this - as if suddenly aware of the risks - you ask whether you, or anyone, can "succeed." If you go on in this way, thoughtlessly mirroring yourself in an obituary, you will soon be writing your epitaph - in two senses.
Do what you can - and the task will rest lightly in your hand, so lightly that you will be able to look forward to the more difficult tests, which may be awaiting you.
When the morning's freshness has been replaced by the weariness of midday, when the leg muscles quiver under the strain, the climb seems endless, and, suddenly, nothing will go quite as you wish - it is then that you must not hesitate.
