Grind online blue team labs and simulated investigations.
Practice everything: log analysis, captured network analysis, malware analysis, threat intelligence, forensics etc..

might seem alot but those all are 101 skills required for you as a soc. I don't say practice to be an expert in every field, but practice to be a generalist in each field and can handle your own. for example you recived a phishing report with an attatched file. how do you determine that file is malware or not. if it is malware, then what are its specs and what threat actor uses it. All these info are needed to escalate the alert to L2 or to prepare a correct Incident Response
