Gas is only really useful when 'onsite' with no power available.
Use the right amount of heat for the job (temperature controlled iron or 
separate irons for different jobs).
Be aware of surrounding components.
Use good quality solder.
Use good quality flux.
Always, always tin your tip, on each and every use.
