1. Use a soldering iron that can hit 400, and use a needle tip 2. Use leaded solder - lead-free is a pain. If you're not doing this for hours every day, even without ventilation, you'll be fine. 3. Heat the pads you're soldering to, not the solder. I used to tell kids to hold the iron to the pad for a count of three, then feed the solder in. 4. Two additional tools I find helpful - a solder sucker and copper wick.
From memory when I ran a production line with soldering stations ventilation is equally (and possibly more) important for lead free solder.
