How can I set environment variable permanently through shell script?

Question

Let's say I have a script:

#!/bin/bash
echo $1
if [[ ! $1 ]];then
echo "True"
fi
export ABC="/home/aashish"

ABC is not available after the execution of this script. How can I make that variable persist after the execution as well?

No way. Have you read What scopes can shell variables have??
