It's far too much to say that effective hoping is the only - or even the biggest - part of what it takes to succeed. If 14% of business productivity can be attributed to hope that means 86% is dependent on raw talent fickle business cycles the quality of the product you're selling and often pure dumb luck.
If you desire to be pure have firm faith and slowly go on with your devotional practices without wasting your energy in useless scriptural discussions and arguments. Your little brain will otherwise be muddled.
