When you say “tactics,” you are referring to different actions or steps that are needed so that you will be able to accomplish the strategy that you may have in mind. This means that if you would like to do tactics, there are various steps that you have to take in mind and you have to make sure that you will do things properly. When you say “strategy,” this is a bit different. You are referring to an action that you are going to do so that you can reach your goal. There are instances when the strategy that you are planning to use may not prove to be effective. You can change your strategy and this is possible but you may not be able to do it quickly because strategies will also require some time to think about properly.
There are a lot of people who often confuse the usage of tactics and strategy, thinking that these two are the same. Tactics are normally used to signify that there are some objectives that you would like to gain from the situation. For example, you know that you would like to do mountain climbing. You need to come up with tactics that will allow you to be motivated to climb the mountain. You may also want to motivate other people to climb a mountain with you so you will use tactics for that. When you say strategy, you would be thinking about the methods that you can do so that you can effectively climb the mountain.
