Practising at home is a very good suggestion. Here is another, use only the tools that you carry on the bike. Don't go after the good tools in the stay at home box. That is how I found out which brand of cute little tire levers snap like toothpicks and which cute little mini-pump doesn't blow but sucks. Beats walking! It helps to install tires so that the label is adjacent to the valve and if there is a label on both sides of the tire, use a sharpy to mark the drive side. That way you have a reference point when you look for holes. Carry something to boot tires. The tip about putting a little puff of air in the tube before reinstallation is golden as well....you'll never pinch a tube that way (almost). If you keep biking, unfortunately, you will get rather good tire repair!
