It’s not the end of the world if things go wrong. But if they do take responsibility. This was your idea remember? Be flexible and prepared to alter your plan. There’s always tomorrow.
Did you pick something too difficult? Overfacing yourself or your horse always ends in trouble. Keep your aims small and most importantly achievable. The only pressure is coming from you.
Was the weather against you? Be honest, who can concentrate when it’s blowing a gale or raining in bucket loads? Perhaps a trot round the block or a day off would have worked better.
Whatever the reason, don’t dwell on it. Never feel like you have wasted your time. You always learn something – even if it’s what not to do next time!
