Success without significant struggle is a bubble waiting to burst. When you struggle, mind not ... for when your success will sustain , you will realise what made it stick-fast.
You may borrow lessons from JW Rowlings who was rejected 12 times by publishing houses who saw Herry Potter as a weird script or Thomas Edition's rejection of thousands of material before establishing the carbon filament night-bulbs or early failures of Walt Disney.
Failure did not make them lose. Struggle made them stick on and so they succeeded.
Don't pity a struggler ever. Rather make friends with him. Invest in him. For he is a big man in the making, soon.
