From Thomas Witherspoon's excellent QRP blog - qrper.com:
We used to say in the Army, "better is the enemy of good enough". Amateur radio operators are always saying, "If my rig just had (name a feature, any feature) I'd have been able to snag that last rare DX station that only activates once a year". Yet it's funny how life goes on without that last rare DX station.
So don't worry about not having the latest and greatest. What you have is good enough. Go to the field and 'run what you brung' (as they used to say in NASCAR), and have fun!
