Whether you're attacking or defending is immaterial : you're all fire and brimstone either way. Once you realize that someone is hostile towards you, you're not likely to wait for the other person to launch an attack. You'd much rather be the first one to do so. However, your best strategies are likely to be those which you frame in conjunction with others. When carrying them out, you need to be careful that you remain objective and focussed, otherwise you're likely to lose the advantage. You must also be careful not to precipitate the action but to wait for the right time to strike, as often your impatience tends to get the better of you.
Keep in mind: That your worst enemies are likely to be those you've helped in some way.
