I've owned 4 cards over the last 7 years. The biggest lesson: a card that fits your spend pattern beats the 'most rewarding' card on paper. A 5% cashback card you actually use daily will give you 10x more value than a 10% card you use once a month.

I have had a hard time getting this card approved twice. The third time I applied after a 10% salary hike and got instant approval. Banks re-check eligibility every time. If you got rejected, improve your income proof / CIBIL and reapply after 6 months.
